Abstract
Vascular compression devices with an inflatable chamber are disclosed. The inflatable chamber of the vascular compression devices can be inflated and then deflated with a liquid with ultrasound properties similar to biological tissues. Ultrasound waves may be applied to the vascular compression device and may propagate through the vascular compression device and into the biological tissue of the patient to produce an ultrasound image to determine the patency of the vessel.
Claims14
A vascular compression device, the vascular compression device comprising:
- a substantially rigid frame, the frame comprising an outer surface and an inner surface;
- a flexible sheet coupled to the frame;
- a chamber at least partially defined by the inner surface of the frame and the flexible sheet;
- a coupling medium disposed on the outer surface of the frame;
- a second flexible sheet coupled to the outer surface of the frame;
- and
- a second chamber at least partially defined by the outer surface of the frame and the second flexible sheet,
- wherein the second chamber is disposed outside the frame, and
- wherein the second chamber is configured to be inflated with a liquid.
A vascular compression device, the vascular compression device comprising:
- a substantially rigid frame, the frame comprising an outer surface and an inner surface;
- a flexible sheet that is coupled to the frame;
- and
- an inflatable chamber that is at least partially defined by the inner surface of the frame and the flexible sheet,
- wherein the inflatable chamber is configured to be inflated with water, and
- wherein along a portion of the vascular compression device, the inflatable chamber has an upper surface and a lower surface and an ultrasound probe is engagable with the upper surface of the inflatable chamber and some of the ultrasound waves from the ultrasound probe only pass through the inflatable chamber.
